The term for a substance that can dissolve in a solvent is "soluble." In chemistry, solubility refers to the ability of a solute (the substance to be dissolved) to be integrated into a solvent (the medium doing the dissolving) to form a solution. Solubility can vary depending on the nature of the solute, solvent, temperature, and pressure. For example, sugar is soluble in water while oil is not. Understanding the solubility of different substances is fundamental in fields such as chemistry, biology, and environmental science, as it affects reactions, processes, and the behavior of solutions.
